Question about JVC AV-48WP30 48" Rear Projection Television

2 Answers

Clicking Sound So I replaced the green CRT along with the convergence ICS. The Tv would turn on before and now the blue LED comes on, but there is no picture or sound and a clicking (surging sound) is coming from a component inside. It also will not power off without unplugging it. Any Ideas??? Thanks

    I cleaned up the solder joints and now the clicking is gone, but now when I power up it is like it just kicks back off and the front led is blinking at 0.1 sec intervals. What now??

    I cleaned the solder joints up again and used a magnifying glass. Still same problem.... The sound was coming from the horizontal drive transformer I think. What now??

    Well the souund is gone now. It just powers up, and as soon as the high voltage comes on it turns off and a minute later the led flashes.

It was a clicking sound, but right before it quit it became a cracking sound. It no longer makes any sound just sounds like it is turning off.

HELLO. YES U NEED TO GO OVER WHERE SOLDERED THE NEW CONVERGECE ICS AND CHECK THEM TO MAKE SURE THAT U DO NOT HAVE, ANY OF THE CONCETION'S TOUCHING EACH OTHER.!!! AND THAT THERE IN THE SAME PLACE WHERE THE OLD ONE'S WAS HOOKED UP. TO THE BOARD.!!! AND ALSO CHECK THE REEN CRT GUN U PUT IN AND MAKE SURE THAT NONE OF THE WIRE'S ARE TOUCHING ANYTHING.!!! ON THE BOARD OR ANY WHERE ELSE ON ANY OF THE BOARD'S .!!! AND THAT THE WIRE'S ARE HOOKED UP THE WAY THE OLD ONE'S WAS. HO[PE THIS HELP'S U. "GOOD LUCK"

    hello. ok you say that the sound is coming from the horizonal drive transformer.? you think.!!! well. u need to know for sure .!!!. what.??? is making the sound. a good way is to use a old long paper towel tube.!!! to listen with .!!! to try to pin pont where the sound is comming from.!! for sure. !!! try that and let me know . ok !!

Unplug the power to the convergence board. If it turns on, you still have a problem in the convergence circuit.

Hitachi 51UWX20B no sound, no picture, blinking green LED


The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.

3 blinks is the error code for the convergence ICs. You need to replace both STK392-110 convergence ICs. You can get replacement ICs at the following link and they provide installation instructions with pictures.

Convergence


If the red isnt responding via the remote you will need to replace the STK392-110 Ics as the service menu adjustment will not correct it 100% due to the IC being faulty and the red and half the green is controlled by one IC and the blue and other half of green is controlled by the second IC so without changing both ICs the set will progressively get worse. Both ICs are stk392-110. You can get replacements at the following link along with instalation instructions

double check the wire connections, as the filaments not being lit makes me thing a wire isnt connected properly, or one may have been loosend while doing the convergence repairs.

Convergence ICs


the green is half controlled by half of each of the convergence Ics meaning green horizontal is controled along with the red and green vertcal is controlled along with the blue Ics. So if you have replaced both Convergencs ICs the problem is most likely a resistor that is in the green circuit. You will need a schematic to locate which resistors are in the green vertical and horizontal convergence circuit

the convergence ICs have shorted and thats whats shutting down the set. Its an easy repair you have to replace both the Convergence ICs they are STK392-110 ICs you can get replacements at the following link and they provide free instalation instructions with pictures and also free tech support. Heres the link.

There is no chip for the green, Unless he is refering to the convergence Ics as there are two of them and one controls red convergence and half green, and the other controls blue convergence and the remaining green. Those ICs are 20.00 each and take about 30 minutes to replace both. Is your set experiencing a 3D type of picture?
